DATA / Read model
Data-source coverage, provider state, and source roles.
DeltaXPI uses multiple independent evidence sources. No single provider is required for system operation. Provider availability affects evidence coverage rather than overall system availability.
Presentation states only — no coverage evaluator or percentage calculation.
Provider status, authorization, capability state, and policy restrictions are separate presentation concepts.
Policy restrictions: Access and output policy not connected.
Policy restrictions: Example limits apply to access, retention, and output.
Policy restrictions: Marketplace use remains restricted until authorization and policy review are complete.
Unavailable does not mean system failure.
Usable, restricted, and missing providers remain visible independently.
